Had my CAT installed here 3 years ago due to being stolen, CAT disintegrated inside due to up stream issues. But they handled it so well and found me a reasonably priced and CA approved CAT for my vehicle. Highly recommend. He explains it very well and my mechanic husband approved so im happy. read more

This place really takes care of the customer. Ricky is a solid dude very knowledgeable and helpful. I highly recommend this place.

Absolutely outstanding customer service and overall experience. From the first phone call to the completion of the job Speedway was honest and provided a quality work product. Highly recommend the Rancho Cucamonga facility. read more

The down pipe out of my bank 1 catalytic converter in my Chevy Traverse had popped out. I was worried that the cat would need replaced and it's near impossible to get access. Albert and his tech were able to weld it back in place and get me back on the road in less than 1 hour. Great Job! read more

Amazing customer service experience!!! Very hard to find an honest car spot ..but luckily I have! Totally explained my car's issue clearly, and didn't try to milk me, as many car places do. Problems with your muffler??...look no further..this is the spot for you!! Thanks Armen!! read more

Last week I was on my way to work when I noticed that my Rogue sound like a roadster... I took it Pep Boys in Upland that told me it was my catalytic converter, it some how had broke off. They recommended this place. Excellent customer service from the moment I walked in, quick and efficient. Located between Enterprise Car Rental & Goodwill on Foothill Blvd across the street from Del Taco. I would not hesitate to return for any repair I might have in the future or recommend to anyone that needs their services. Respectfully Reviewed. read more

Speedway Muffler - Excellent service - Auto Parts & Supplies Near Me - Upland, California

When I needed to replace my catalytic converter -- it was suggested by my "usual mechanic," that I should take it to Speedway Muffler. I dealt primarily with Armen (supervisor?); and Paul (one of his lead technicians). I was advised of options available, and had my work done "seamlessly" (and in a little shorter time than I was expecting). I would ABSOLUTELY recommend SPEEDWAY MUFFLER -- to those who are seeking Excellence in Knowledge, Competency, and Workmanship (for a very reasonable co$t : -) read more

Had a muffler installed here on my car. The work was good quality. The welds broke on one of the tips they installed, so one side is crooked. Otherwise, ok. The price than he'd from when I asked originally. This did not sit well with me. read more

Good group of people here, were able to work with me to get exactly what I wanted. Mario was very efficient and listened to my wants. Thanks guys! read more

The Manager Armand (i hope that is his name) go above and beyond customer service. Very clear, and informative. Takes time to explain your needs in detail. He makes you feel important! -Jamie read more

I just wanted to send my deepest gratitude to Armand for being very helpful and informative and honest with me about my car I would definitely recommend him very highly awesome personality. Thanks again God Bless read more

I went into this not expecting one thing from this company. However they delivered so much, this gentleman I think his name was Paul was such a cool guy. I believe he was the mechanic or the main guy. He walked the car with me and showed me a on sight Appraisal. And he told me that he would be able to get it done on sight less than two hours. (Which means he's putting customers first) Thank you for helping me with my Mustang, I really appreciate your team's kindness and work ethic! read more

Would recommend being careful with this shop. I was young and dumb and got a muffler and resonator delete; well the shop kept both muffler and resonator without me realizing what happened months later. They also like to cut corners which ever way saves them time. read more

These guys know their stuff Super fast Great work Great price These lads are bad ass Need a muffle here's where you go Thanks lads Love the new super 44 read more

These guys did me a favor and bent my tunnel reinforcement plate back to normal for me on my Dodge Charger for about $60. Great service and just wanted to say thank you. read more

Great people. I had to have a new muffler put in as mine was punctured by something while driving. Did a great job.

This is my 3rd car I have brought them and I drive from South OC even. They are courteous, knowledgeable and aim to please. This is what customer service is about. Not to forget the willingness to help provide exactly what the customer wants. Highly recommend. read more

What can I say. This place is AWESOME. The replaced my rusted, stock system (on my 2019 Silverado 3500 HD) with a Magnaflow Dual catback system that I purchased and brought in for them to install. They wrapped the job up in about 2 hours and I could not be more pleased. The welds were flawless and the level of professionalism was outstanding. These guys are super nice and labor prices extremely reasonable. This is how you run a business. You have made a customer for life! read more

These guys are the real deal. You can tell when you are working with a real pro. I went in to put in an aftermarket exhaust, and it was not an easy install because it was a universal piece, but they made quick work of it. The man that worked on my truck made it look easy. It's like watching a kung fu master the way this man moves. No wasted motion, moves like water. I was lucky to bring it in, because they found a big problem that they brought to my attention. It could have e been a disaster in a short while, and they were kind enough to fix it on the spot. I can see why these gentlemen have a high rating. They are the best at what they do and they are very reasonably priced. I would definitely recommend this shop to anyone that needs exhaust work done. I will be returning whenever I need any work done. 5 stars all around read more

I appreciate this shop so much!! Their customer service is amazing and they provide excellent work. They have been so helpful, not only with my car but with my daughter's car as well. My daughter's car has two catalytic converters that I assumed needed to be replaced. They were very honest and said only one needed to be replaced and that they didn't want me to come out of pocket if I didn't need to. They also fixed a couple of leaks I had without charging me extra. It is very rare to find a shop with this type of honesty. I will never take my car to any other muffler shop and I live over an hour away. Thank you guys for all your help! read more

I took our Mazda cx5 here after the dealership said an exhaust gasket needed replacement. They put it on the life and called me in to show me the gasket was fine and it was only a little corrosion, and nothing to worry about. Dealership wanted $250! Speedway didn't charge me anything, but I gave them a $20 tip and a big thank you! Honest shop, I'll go back when I need to. read more

I just had a catalytic converter cage installed on my '05 Honda Accord. Great family owned company, both father and son are very kind and honest people and was treated so well from start to finish. 5 stars! I highly recommend this muffler shop! read more

I wanted to get my cat shield installed on my tacoma. I called and spoke with Armen who was extremely helpful and answered all my questions. I was able to schedule install same day.

Speedway Muffler - Had it up on the lift within minutes of arriving. - Auto Parts & Supplies Near Me - Upland, California

Other places said it couldn't be done. They said it was impossible to put a center exit on a Civic Hatchback EX. However, Mario and his crew were able to do it! Mario is a true craftsman and built a custom exhaust for my Hatch and it came out stunning. The sound and look was just what I wanted! They did a resonator swap, muffler delete, and put in tips for a modest price! Speedway Muffler took care of me! When no one else was up for the job, they took it and exceeded my expectations! Civic 10th gen owners, look no further, this is the place! read more

Cat was stolen, had a difficult situation & Paul helped to navigate me through the process. Will refer to all my family & friends.

Needed a catalytic converter. Found business on Yelp. Initially contacted by phone. Got a good feeling. Place was clean, welders experienced and courteous. Car was ready as promised. Will return again if needed. read more

I arrived unsure of what I needed and the guy in the front took the time to educate me and speak to me of my options and even printed a paper to show me the California law. They fixed my car in approximately three hours and I was truly impressed how well they took care of me and my car. They even followed up with me afterwords regarding the work they did. read more

Rafi and Co were super responsive and helpful. I had to get my cat converter replaced and they helped me through the process. They were able to get it done in one day. Highly recommended read more

Well I'm a happy girl! I had my 2015 6 cyl Mustang stock muffler upgraded to what it should sound like. All done in a very timely manner! Nice people too. I highly recommend them! read more

Referred by my mechanic, I think this muffler bar sets a high bar for competitors. They caged the catalytic converters on my Prius after an attempted theft for a very reasonable price and offer custom systems for those vehicle models that don't have a cage already out on the market. Appointment time was honored and their expert installers get the work done quickly. Highly recommend these muffler/cat experts. read more

Took my quite Eccoboost and made her sound sexy! Fast and friendly service! I'll never go anywhere else! Thanks guys read more

I called the day before I showed up. They don't really take appointments so it's first come first served. I was there waiting at 7:30am. They open at 8:00 and I was on the road at 9:30am. Armen was great to work with. Extremely friendly and offered something to drink while I waited. Mario was working in the garage doing a muffler delete on my Mercedes. Mario is a master! I told him he was an artist and did great work! The pipes were custom bent and installed like the pro he is! Highly recommended... ***** read more

These guys took the best care of my ride. I was there with my older VW and had new cat, stainless exhaust and magnaflow installed in quick order. Honest and straightforward, reasonable price. Thanks! Inadvertently placed review at rancho speedway. I was in Upland. I apologize for the confusion. I will delete rancho review. read more

Fast speedy service! Was actually referred to these guys by another mechanic into when his machine went down! That says a lot! Would recommend this place to anyone! read more
